AUGUST SCHNEELOGH, OF NEW 'YoRnN, Y., ASSI'GNOR or ONE-HALF TO E. C. STEARNS & (30., OF SYRACUSE, NEW YORK, A CORPORATION OF NEW YORK, AND ONE-HALF TO JOHN E. THOMAS, OF NEW YORK, N. Y.

RIBBON MECHANISM FoR TYPE-WRITERS.

Specification of Letters Patent.

Patented April 2,1907.

Original application filed April '7, 1900, Serial No. 11,993. Divided and this application filed May 9,1901. Serial No. 59,361-

a subject of the Empire of Germany, residing in the city of New York, borough of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Ribbon Mechanism for Type Writers, of which the following is a specification, bein a divisonal application of the application led April 7, 1900, Serial No. 11,993, reference being had herein to the accompanying drawings.

My invention relates to type-writing machines; and its object is to provide an im proved means of maintainin the ribbon in operative relation with the platen and typebar, and I attain this object by the devices illustrated in the accompanying drawings, in which similar figures of reference indicate similar parts throughout the various views.

The device illustrated and described herein is shown adapted to the'type-writing machine shown and described in said application for patent filed April .7 1900, Serial No.

Figure 1 is a longitudinal section on line 1 1 of Fig. 2. Fig. 2 is a partial plan view. Fig. 3 is a sectional view of the ribbon-spool. Fi 4 is a detail perspective view. Fig. 5 is a detail perspective view.

Referrin to Figs. 1 to 55, inclusive, 2 is one of the keyevers ofthe machine operatively connected with type' lever 3.

4 is the universal bar of the machine.

181 is a rod extending underneath the keylevers 2. Attached to each end of said rod 181 is arm 182. Journaled on frame 1 of the machine is shaft 183, to which said am 182 is also attached, and by means of spring 184 said rod. 181 is held in-contact with the keylevers. Attached to said shaft 183 is connecting-arm 185, which at its other end is operatively connected with connecting-link 180;

Oscillating lever 64 is fulcrumed on support 65, extending from segment 66.- Said oscillating lever 64 is connected by the ordinary fork-and-pin device with the ribbonide 67, said uide 67 working on typear guide 68 and being guided in its movement by-screw and slot 70 71 sothat with each movement of a typekey lever said ribbon-guide 67 is raised or lowered, as the case may be. Said lever- 64 is provided with a fork or inclined slot 177 and said su port 65 is provided with a bent fork or aent slot 178. Said lever 64 is operated by means of pin 179 on link 180 working in said inclined slot 177. Said pin 179'also works in bent fork 178, audit will be readily understood that when the slot 177 is brou ht to register with inclined upperportion of movement of'pin 179 .within the same will not operate so as to cause any further movement of lever 64. The ribbon-guide will remain stationary whatever the motion of its operating device may he provided fork 177 and bent fork 178 register with each other. Shaft 169 may be connected to ribbon-spool sh'afts 172, each having at its upper enda hinged catch 173. The ribbon-spools are adapted to fit over the ends of said shaft 172, and it will be readily understood that by putting one of the catches 17 3in its notch 175 in one of the spools and leaving the other catch free from the other spool that the ribbon 176 will be wound one way and upon reversing fork 178 the the arrangement of the catches the ribbon will be wound the other Way.

that I claim, and desire to secure ters Batent, is-

1. In a type-writer, the combination with the frame, type-bars, ribbon and o erative connections between the respective ey-levers and typebars, of a ribbon-guide adapted to move rectilinearly and vertically, guiding mechanism positively .to guide the ribbon-guide in said rectilinear vertical movement and connections'operated b all the key-levers to raise the ribbonui e in a straight line to a point immediate y in front of the platen during the first ortion of the downward movement of the l ey and to lock the ribbonuide in said position during the continued downward movement of the key, until the by Leti type has struck.

2. In a type-writing machine, the combination with the frame, the platen, the keylevers, the type-bars and connections between the key-levers and the type-bars, of the support formed with bent forks or bent slots of which the upper portions are arran ed at an angle to the lower portions, an osci lating lever formed with an inclined slot and journaled on said support, the

platen, keys, key-levers, types,

i pp

, clined slot substantially v the upper portion of said bent slots, the rib ribbon-guide suitably supported on the frame and connected to the oscillating lever, a linkhaving a portion engaging with said bent slots and with said inclined slot, and

connections between the key-levers and thev link whereby the link israised on the depression of each key-lever.

3. In a type-writing machine, nation with the frame, the platen, the'keylevers, and type-bars suitably supported forwardly-extending branches, both of said branches being formedwith corresponding opposite bent forks or bentslots of which slots the lower p0 tions arevertical and the I 'ortions inc ined, an oscillating lever ourna ed-on'said support and having an inbon-supporting mechanism suitably supported on the frame, operative connections between the ribbon supporting mechanism and the oscillating lever, a link, a pin on said link engaging with said inclined slot and said bent slots and connections between the type-bars and the lower end of said link whereby the link is raised at the depression of each type-ban 4. In a type-writing machine, the combination with the frame, the platen, thekeylevers and the type-bars suitablysupported on. the frame, of aribbon-guide, a ribbonguide mechanism supported on the frameand fittedto the guide, a slotted support on the i'rame, a slotted oscillating lever journaled on the support and connected to the ribbonguide mechanism, a link engaging with the 2 the combion Y the frame, of connections between the keylevers and the type-bars, a support hav ngcorresponding to' slots in the support and in the oscillating lever, and connections between the key-levers and the link whereby the' link and the oscillating lever are both raised during the first portion of the downward stroke of each keylever, but during the last portion of the downward stroke th link only is raised, while the oscillating lever, and ribbon-guide mechanism are locked firmly in printing position.

5. In a type-writer, the combination with the frame, platen, keys, key-levers, types,

type-bars, ribbon and operative connections support and connected to the ribbon-guide,

an element fittedto move simultaneously in. suitable slots in said-lever-support and oscillating lever, and connections to said element operated by the depression of all the keylevers, operatin to raise said element in said support-slotand thereby swing up the oscillatinglever and raise the ribbon-guide to a oint immediatelyin front of the platen durmg. the first portiofi of the downward move- .ment offthe key and to lock the ribbon-guide in said position during the continued downward movement of the key, until the type has struck.

In testimony whereof I have hereunto set my hand this 8th day of May,-1.901.
